To all whom, it may concern Be it known that we, CHARLES W. CLoUGH, ALFRED N. CLoUGH, and WILLIAM 0. SPRING, citizens of the United States, 'residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Combination Folding Cot and Table, of which the following is a specification.

An object of this invention is to provide a device of this character which can be used as a single cot, as a double cot and as a table of different lengths, according as the various elements are arranged relative to one another.

Another object is to provide a, device of this character which, when folded, will be of minimum size and when extended for use will be of maximum strength.

Other objects and advantages may appear in the subjoined detail description in connection with the drawings filed herewith.

Fig. 19 is a plan section on line indicated by 00 421 Figs. 3 and 10.- Fig. 20 is an enlarged sec. tional elevation on line indicated by of -m Fig. 1, omitting the cover. Fig. 21 is a fragmental sectional elevation analogous to Fig. 20, but showing the parts in folding positions. Fig. 22 is a fragmental inverted plan view of Fig. 20. Fig. 23 is an inverted plan view of Fig. 24. Fig. 24 is a side view of the invention folded or collapsed, the side rails being partly extended. Fig. 25 is an inverted plan view of the cover folded as in Fig. 9.

There are provided telescoping side rails each comprising end sections 1, 2 and an intermediate section 3; and there are provided telescoping folding end rails each comprising end sections 4, 5 and intermediate sections 6, 7, the end sections 4, 5 being pivoted at 8 to links 8 which are in turn pivoted at 8 to the side rail sections 1 or 2, as the case may be, and the adjacent ends of the intermediate sections 6, 7 being pivoted at 9 to links 10. The pivots 9 extend through longitudinal slots 11 in said link 10, so as to allow for endwise movement .of the end rail sections 6, 7 relative to the link 10. The link 10 is provided at its opposite ends with latches in the form of pivote 11 dogs or hooks 12 designed to engage stops in the form of pins 13 in the sections 6, 7 when said pins are seated in notches 13' at the ends of the link and the pivots 9 are at the inner ends of the slots 11' {the dogs when thrown out of commission releasing the pins 13so as to allow the sections 6, 7 to be drawn sufliciently far to disengage the pins 13 from the notches 13 so that said pins 13 will swing past the ends of the link 10 when the sections 6, 7 are folded toward one another as in- Fig."21. ,The dogs 12 are normally held in latching gosition by coil springs 12' clearly shown in. ig. 22.

The sections 4, 6 are 'adjustably locked against relative movement by the device' 4, 6 are adjusted relative to one another to' bring one of the holes into registration with the detent, there being a coil spring18 between the opposite end of each trigger and thesection 4 so as to normally hold the trigger in the latching position. The rail sections 1 to 8 .'nclusive are in the form of channel irons and constitute a 2m rectangular frame and said frame is rovided at each of its corners with a fol ing or jack knife leg formed of upper and lower sections 19, 20, the upper section being pivoted at 21 to the link 8', as clearly shown 5 in Fig. 15.

The leg sections 19, 20 are in the form of channel ironsand are provided with suitable means to lock them intheextended or unfolded position and for this purpose, as

clearly-shown in Fig. 13, the upper sections 19 are provided with pivots 22 engaging slots 23 in the upper ends of the lower sections 20, the distance between the lower ends of the slots and the upper ends of the sections 20 being greater than the distance from the slot to the sides 24 of the leg section 19, said sides 24 thus forming stops to hold the legs against folding when the pivots are at the lower ends of said slots, and the distance between the upper ends of the slots and the upper ends of the sections 20 being less than the distance from said slot to the stops 24 so that, when the pivots are in the upper ends" of the-slots, the legs may be readily folded as indicated in dottedlines, Fig-13. The upper leg sections 19 are pivoted at 25 to the lower ends of folding end braces,

comprising lower and upper sections 26, 27 which are pivoted together at 2 8, the upper sections 27 being pivoted at 29 to the end rails. The upper sections 27 are provided at their lower ends with stops 30. designed to seat in notches 31, see Fig. 16, of

- the lower sections 26 when thebracesare in extended position so as to hold said braces ing being due to spacing collars 31' sur rounding the pivots 8 between the inner faces of the end rails and the outer ends of the links 8.

The pivots 22 of the legs at one end of the frame extend through the lower ends of folding sectional side braces 32 each composed of upper and lower sections 33, 34 pivoted together at ,35 and each provided with a stop andslot similar to the stop and slot. 30, 31 above described and indicated on the drawings by the same reference characters. The upper brace sections 33 are each pivoted at 36 to the side rails. At the other end of the frame other side braces similar to those just described are provided and are designated by the same reference characters, but said other side braces are pivoted by pivots 36 to the legs at said other end.

The frame is provided transversely near its middle with a folding V-shaped brace formed of sections 37, 38 pivoted to one another at 39, the upper ends of said brace sections being provided with hooks 40 designed to hook into holes 41 in the inner sides of the intermediate side rail sections 3, as clearly shown in Fig. 11.

The side rail sections 1, 2 and 3 are provided in their outer sides with holes 42 to receive studs 43 fastened at intervals along flat strips 44 which are fastened along the side margins of a cover 45 constructed of suitable material such as canvas or the like, so as to form a suitable narrower support for bed clothing or dishes and the like. Each of the flat strips 44 is approximately of the same length as the side rail sections and the cover 45 is provided with slits 46 between adjacent ends of said strips as clearly shown in Fig. 25 for the reason hereinafter-set forth. The cover 45 is provided with side extensions 47 having flat strips 48 attached thereto, said strips being similar to the strips 44 and said extensions being provided with slits 49 between the adjacent ends of strips 48. The strips 48 are provided with studs 50 designed to engage the holes 42 to form a wider support for bed clothing, not shown.

The cover extension 47 along the strips 48 is provided with snap sockets 51 designed to engage snap studs 52, fastened to the cover 45 when the studs 43 are in the holes 42, as clearly shown in Fig. 9, so as to hold thev extensions 47 folded flat against the under surface of the cover and out of the way of any person seated at the table. The cover 45 is also pr0vided,as clearly shown in Fig. 25. with snap studs and snap sockets 53, 54 designed to hold one end portion of the cover folded flat beneath the remaining portion when the parts are arranged in the contracted or shortened position shown in,

solid lines, Fig. 8.

In order to stretch the cover 45 and take form of toggles constructed as follows: Re-

ferring more particularly to Figs. 6 and 17, the end rail sections 5 are provided with toggle links 55 pivoted at 56 to" the sections 5 and pivoted at 57 to operating toggle levers 58 which in turn are pivoted by hook shaped pivots 59 to the sections 7 each of the operating links 58 being provided with a stop in the form of a laterally extending lug 60 designed to engage a slot 61 in the link 55 when the toggle is in the extended position shown in Fig. 6, so that the toggle will not collapse but will hold the sections 5, 7 extended against the tension of the cover especially when the cover is supporting a weight such as that of a person or persons.

The cover 45 is provided at or near the middle of its ends with hooks 62 designed to hook over the adjacent ends of the end rail sections 6, 7 so as to support the cover at its ends.

In practice, assuming that the device is in the folded or collapsed position shown in Fig. 24, to set up the'device with the parts arranged to form a single cot, the side rails will first be spread apart as indicated by the arrows a, Fig. 23, and then the end rails will be straightened to bring the dogs 12 .into locking arrangement with the pins 13.

Then the end braces will be extended to brace the frame thus produced. Then the end rails will be turned through an angle of 90 degrees around the pivots 8" to swing the legs away from the side rails into vertical position relative to the side and end rails, and the side braces will be extended to hold the legs in upright position, and then the side rails will be drawn out to their full length, thus completing the arrangement shown in solid lines in Fig. 10. Next the cover 45 with the extensions 47 folded in under and fastened by the snap studs and sockets 51, 52 will be fastened in place on the frame by inserting the studs 43, into the holes '42. 1

To arrange the device as a table, the lower sections 20 of the legs will be swung downward away from the upper sections 19 and moved endwise to shift the pivots 22 in the lower ends of the slots 23, thereby locking the legs in their fully extended positions so as to bring the-cover 45 to a convenient height for use as a table top. If the cover 45 after fastening in place is not stretched sufficiently taut, the toggle devices as in Fig. 8 by telescoping the side rails, whereupon one end of the cover 45 will be folded in under the middle portion of the cover and fastened in place by the snap studs and sockets 53, 54.

To form a double cot, assuming that the parts are in the positions shown in solid lines in Fig. 10, the end rails will be drawn out to their full lengths, and then the studs 50 will be inserted in the holes 42, thus completing the arrangement shown in Figs. 1, 2, 3 and 7. v

To fold or collapse the device from any of the positions above described, reversal of the movements just described will bring the parts'in the folded positions shown in Figs. 23 and 24.

The-foregoing will enable those skilled in the art to construct and operate the device.
